Title: Light controlling sheet
Inventor: HASHIMOTO AKIYO
IPC: G02B5/02
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a light-controlling sheet which does not produce such a pattern of sheets that they are adhered to each other or a pattern like Newton rings even when plural sheets are laminated for use, and which has excellent appearance by forming a resin sheet having changes in the thickness in one direction in such a manner that the change rate has the max. and the change rate of the thickness and the max. amplitude of the changes of the thickness satisfy specified condition. SOLUTION: This light-controlling sheet has changes of the thickness in one direction and the change rate Δt of the sheet is controlled to a range satisfying 0.3 μm/mm<=|Δt|<=1 μm/mm. The max. amplitude A of the changes in the thickness ranges is controlled to a range satisfying 5 μm<=A<=15 μm. In the aforementioned expression, Δt represents the thickness change rate of the sheet, and when recesses and projections are present on the surface, the recesses are neglected but the film is considered as flat. A is the max. amplitude of changes in the thickness. Thereby, the film does not produce a pattern of a tightly adhered state or a pattern like Newton rings but has excellent appearance, and the film is preferably used for a liquid crystal display screen or the like.

Title: Bias matnetic field inverter
Inventor: KAWAMURA ICHIRO
IPC: G11B11/10
Filed: 1989-12-29
Abstract: PURPOSE:To shorten the inverting time of a bias magnetic field by supporting a bar-shaped magnet magnetized into double poles in a width direction so as to be turnable around its longitudinal axis, and rotating the bar-shaped magnet until it strikes a stopper member by passing a current through a coil. CONSTITUTION:When coils 2, 3 are energized so that the lines of magnetic force of the direction E are generated, two S-poles of the magnet 1 are attracted by the coils 2, 3 respectively, and N-poles are repulsed by the coils 2, 3, and the magnet 1 is rotated in the direction G1 around the axis 6. As a result, the magnet 1 is brought into contact with plates 4, 5, and is stopped as being kept in an inlined state. In such a state, the line of magnetic force due to the magnet 1 and the line of the magnetic force due to the coils 2, 3 are summed, and as a result, a bias magnetic field in the direction Z1 is given to a magneto- optical disk 18. When the current flowing through the coils 2, 3 is reversed, the magnet 1 stopped as being inclined in a reverse direction. In this state, the bias magnetic field given to the magneto-optical disk 18 becomes in a reverse direction Z2. Magnetic force generated by the coil can be used as driving force to rotate the magnet 1, and the inverting time of the magnetic field can be shortened.

Title: Inspection method for resonance capacitor in automatic material-handling vehicle
Inventor: KAWAGOE TOSHIMASA
IPC: G01R31/00
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To obtain an inspection method in which the failure restoration time of an automatic material-handling vehicle is shortened by a method wherein the DC voltage value of an AC/DC conversion circuit is compared with a reference voltage value and the abnormality such as the aged deterioration or the like of a resonance capacitor is detected. SOLUTION: When a capacitance is reduced due to the aged deterioration of a resonance capacitor 22, a resonance frequency is increased, and the electromotive force of a pickup coil 21 at the exciting frequency of a feeder 11 is lowered. Especially, when the resonance frequency is deviated largely from the exciting frequency, the electromotive force of the coil 21 is lowered remarkably, and sufficient electric power cannot be supplied to an automatic conveyance vehicle. In addition, a change in the electromotive force changes a DC voltage value which is rectified by an AC/DC conversion circuit 23. In addition, a voltage detector 30 is installed on the output side of the AC/DC conversion circuit 23, and the voltage value is detected periodically.  As a result, when the output voltage of the AC/C conversion circuit 23 at a time when the resonance capacitor 22 is normal is compared with the output voltage at a time when the capacitor is deteriorated, the deterioration of the resonance capacitor 22 can be estimated.
